Question

If the tangent at a point P to a circle with centre O cuts a line through O at Q such that PQ = 24 cm and OQ = 25 cm. Find the radius of the circle.

Answer 1

Answer:7

Step-by-step explanation:

Pq =24cm

Oq =25 cm

Op=?

Oq^2=pq^2+op^2

25^2=24^2+op^2

625-576=op^2

49=op^2

Under root 49 = op

7=op
